Must be a terrible use-case since these transactions are done on a transparent ledger where the transactions are publicly traceable and certain coins can be delisted and banned from exchanges.

If it is such a great use-case for that, why is it that not only they haven't banned every single cryptocurrency yet, but it seems that tracing these transactions have helped the regulators and authorities into finding anyone attempting to commit fraud and illegal transactions on a public ledger.
